MILK-COOLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 507,730, dated October31, 1893. Application filed November 4, 1892. Serial No. 450,966. (Nomodel.)

.To all whom it may concern:

Be it known that I, SAMUEL M. HEULINGS, a citizen of the United States,residing at Haddonfield, in the county of Camden, State of New Jersey,have invented certain new and useful Improvements in Milk-CoolingApparatus, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to certain new and useful improvements in milkcooling apparatus and it has for its objects among others, to provide asimple and compact apparatus and arrangement of parts whereby the wateror other cooling liquid may be readily siphoned from a spring, tank, orother source of supply and in which a refrigerant cooling device may beintroduced when required to cool the liquid before it passes to the milkcooler.

It has for a further object to prevent the drawing in of air with theliquid. In order to start the device operating, I rst exhaust the air byany suitable means and then admit the Water from the spring, tank, orother supply when the apparatus will continue to be self-operating.

Any form of milk cooler may be employed in connection with the presentimprovement.

Other objects and advantages of theinvention will appear in thefollowing description and the novel features thereof will beparticularly pointed out in the claims.

.The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon,form a part of thisspecification and in which- Figure l. is a side elevation'of my improvedapparatus, showing, in dotted lines, some of the modifications which maybe adopted. Fig. 2 is an enlarged central, vertical section of thestarting cup or receptacle.

Like letters refer to like parts in both views.

Referring now to the details of the drawings by letter A designates amilk cooler which may be of any suitable constructionand supported inany desired manner. The cooler may be located in any desired positionrelatively to the water supply butpreferably loe- 5 low the same so asto avoid the necessity of first pumping the liquid to a pointabove thecooler and then allowing it to flow by gravity. The cooler may bearranged at any required distance from the source of liquid supply andthe refrigerant cooler may be interposed at any suitable point. In thepresent application I have illustrated two forms of apparatus whereinthe refrigerant cooler is interposed.

Referring to Fig. l, B is a tank or other re- 6o ceptacle provided withan outlet pipe b having a suitable controlling valve b and Vconnectionwith a pipe C which may be flexible or rigid as desired. This pipe O hasa branch B which communicates with the pipe O upon tween the said cup orreceptacle and the 7o branch B it is provided with a suitable valve asd. In order to prevent air entering the pipe O withthe Water fromreceptacle Dwhich Would occur were the discharge opening in saidreceptacle of ordinary formI place within said receptacle a verticalpartition D suitably held therein and provided with a depending portiond which extends into the enlargement D2 (which, however, need ynotbepresent) at the bottom of the said receptacle 8o as seen-clearly in Fig.2, providing a passage Way upon each side thereof as seen in said figureand which serves to prevent a circular movement of the water in passingthrough Athe discharge opening of said "receptacle and S5 therebypreventing air from ilowing into the. pipe with the water.

E is a pipe upon the opposite side of and communicating with the coolerA at top and bottom as shown and near its center provided 9o with abranch e with which is connected the pipe E which is provided with asuitable seal to prevent ingress of air and which seal may be of anydesired or well known form. It

may be located at any desired point either as shown at E2 in full linesor at F.3 by dotted lines in Fig. 1. A valve e may sometimes be employedin place of the seal as indicated by dotted lines in Fig. 1.

F is a discharge pipe from the trough A of ico the cooler and throughwhich the milk may be conducted to a can or other receptacle A2 as shownin Fig. 1.

The cooler may be supported by hangers or loops A3 as seen in Fig. land' upon the support A4 may be arranged the receptacle A5 through thedischarge pipe CL2 of which the milk iiows onto the cooler as indicatedin Fig. l.

The operation of this form of apparatus is as follows: The cock or valveb being closed and the receptacle B filled with Water or water beingsupplied thereto, the valve d is opened when the water fiows from thereceptacle D through the pipe C and through the branch B and into thepipe;C and cooler, forcing all of the air therefrom and when the. wateremerges from the pipe E the valve d 1s closed and the valve b openedwhen the water will be drawn from the tank or receptacle B by siphonage.Instead of taking the water from a tank or receptacle it may be taken.from a spring as indicated by dotted lilies 1n Figi, a suitablestrainer G being generally provided and the pipe g from said sprungcommunicating with the pipe C and provided with a suitable valve g whichmay be located at any desired point, either as shown by full lines or bydotted lines in Fig. I. Or connection may be had with both the tank andthe spring as shown, it being understood of course that generally whenone form 1s employed the outlet from the other will be closed althoughsometimes both may be used together.

It may sometimes be desirable to arrange the tank or receptacle upon ahigher plane than the cooler and conduct the water therefrom by gravity;such an arrangement is shown by dotted lines at the right of Fig. l 1nwhich AG designates the tank and a6 the outlet pipe therefrom which isdesigned to connect with the pipe C of the cooler at the point where thebranch B connects in the form shown by full lines. The pipe should beprovided with a suitable valve a5 as shown whereby the supply may becontrolled.

If it is desired to cool the liquid intermediate of thetank and thecooler A,it maybe done 1n this manner: A suitable tank H should beprovided in which is located a coil II in the supply pipe and in whichtank is designed to be placed any suitable refrigerant. In the formshown at the right and upper part of Fig. 1, this coil is simply a coilformed of the pipe A but in the form shown at the lower and central partof said gure the coil is formed of an independent pipe from the pipe Cand having its ends connected with and communicating with said pipe C, asuitable valve c being provided as shown whereby the water in itspassage from the tank or from toman the spring or other source is causedto pass down one branch of the coiled pipe and through the coil in therefrigerant receptacle, thence through the other branch and through thepipe C and branch B' to the cooler. It will be readily seen that by thisinterposition of the cooling device the liquid may be sent on its directcourse from tank B to pipe C or by way of said coil and pipe Il to thepipe C.

Modifications in detail may be resorted to Without departing from orsacrificing any of the advantages of the invention.

Any suitable form of coil maybe employed, but in some cases I prefer theform shown by dotted lines in Fig. l, in which a shallow vat or tank isshown and in this tank or vat is arranged one or morelayers of pipeconnected one with the other by return bend, and H is an overiiow pipefrom the tank or vat. 7LX is a drip cock from the pipes and hX a dripcock from the tank or vat. By this means I obtain better results; Iplace enough water in the tank or vat to just cover the pipes and placethereon a layer of crushed ice; the ice cannot be melted away from aclose position or contact with the pipes as it is constantly settling onthem; the overflow pipe IIX admits of the automatic discharge of thesurplus water as it is formed in the tank. The drip cocks allow of thedraining of the pipes or vat when desired.

iVhat I claim as new isl. The combination with the milk cooler, a liquidsupply and connections between the same, of means for preventing ingressof air to the cooler, with the supply and a liquid p cooling device,interposed between the cooler and supply substantially as described.

2. The combination with a milk cooler, a liquid supply and connectionsbetween the same of an interposed liquid cooling device with means forthrowing it into or out of operative connection, as set fort-h.

3. The combination with a milk cooler, a liquid supply and siphonconnections, of an interposed liquid cooling device and means forpreventing ingress of air to the cooler with the supply, as set forth.

4:. The combination with a milk cooler, a

In testimony whereof I affix my signature in presence of two witnesses.
